Impressively engineered

Chevrolet Performance engineers adapted a unique, electronically controlled port fuel-injection system to the ZZ6 350, using an aluminum intake manifold that has the appearance of a carbureted intake. A fuel-injection throttle body mounted in place of the carburetor allows a traditional air filter to be installed on the engine. The Turn-Key kit includes the distributor and damper installed, starter, fuel pump, air conditioning pump, alternator, single-belt Front-End Accessory Drive Kit, and more.
